This might looks like a mess but if you guys remember there's is the "tradegy" that made kwon daegun soft in the future and an all out brawl shown in a short backstory. Do I feel like this will be simple kwon daegun will faught both side and unlocked "immersion" for the first time either fight both faction alone or with park heejun and the gang which the most likely to happened since based on another short backstory that was shown chapters ago they kwon daegun and park heejun only totally split in highschool where the hierarchy between the two of them was decided then park heejun started doing the "drugs" to immitate kwon daegun immersion to be as strong if not stronger than kwon daegun.
I don't know who you are but I hope you're having a hard time
